Levonorgestrel - took Take Action pill 3 days after unprotected sex. Will it work?

me and my bf had sex 3/14 and he finished in side of me. (allllll of it.) i had started to get weird dreams days after, bloating, cramps, and not to share too much info but when i used to restroom, i noticed i had Diharea. i took the pill 3/17. What are my chances of it working???
